MECHANICAL MOVEMENT.

Specification of Letters Patent.

Application filed Septcmber'm, 1913.

Patented Oct. 13, 1914. Serial No. 789.447.

To all whom it may concern:

Be it known that I, SIGMUND MEs'rnL, a and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and 1m roved Mechanical Movement, of which the following is a .full, clear, and exact description.

This invention relates to hand operated devices such as egg heaters, fans and.the

Among the objects of the invention is'to simplify and improve this class of hand motors whereby they are cheapened in construction and rendered more effective than devices heretofore proposed for the same purposes.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a perspective view of a preferred form of the invention indicating its of the device,

use as an egg beater; Fig. 2 is a side elevation of the rack and pinion portion of the device; and Fig. 3 is a representation 'of a fan adapted to be operated by the hand motor of this invention.

A device made in accordance with this invention may be of any suitable size, and the relative proportions of the parts, as well as the general design and the application may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed. 1

Referring especially to Fig. 1 it will be observed that the' device comprises two prin cipal parts, namely, a shaft 10 and a hand operated actuator'll therefor. The shaft 10 is substantially straight and formed preferably of round rod or wire. At one end it is provided with a polygonal portion 12- upon which is seated a pinion 13 and the pinion is thereby held from rotation independently of the shaft. Said rod may be formed as an extension .of an egg beater dasher 14 formed into a number of parallel loops or fingers of which the central finger 14' is longer than the others and constitutes a pivotal point or bearing in alinement with the axis of the shaft 10.

The actuator 11 is formed preferably of a ends of the coils 16 extend overlap illustrated in the single piece of rod metal or wire and comprises a bearing loop 15 at its middle portlon, said loop surrounding the shaft 10 and constituting the main bearing therefor. From said loop the metal of the actuator is formed into a pair of coils l6 to'increase the resiliency of the actuator at these p0rtions or shoulders and thence theopposite as a pair of hand grlps 17 and 18. The grips 17 and 18 are substantially straight and slightly divergent. Each of these members is formed at its end in a substantially right. angular arm 17 and 18 respectively, which extend toward or each other. The arm 17 is formed with a series of teeth 19 constituting a rack cooperating with the pinion 13. The ex treme end 20 of this arm is bent laterally at a right angle from the plane of the member 17 and its arm 17 stop cooperating with the angle portion of the member 18 serving'to limit the separation of the members 17 and 18 under the action of the elasticity of the loops 16. The

and constitutes a.

arm 18'-terminates in a bearing loop 21 surrounding the shaft 10 and lying between the pinion 13 and the adjacent end of said shaft. It will be noted also that the end of the arm 17 having the angularly arranged point 20 lies between the pinion 13 and the member 18; therefore, the member 18 prevents slipping of the rack along the pinion or displacement of the rack from the pinion in any direction. The pinion furthermore being shrouded prevents longitudinal movement of the rack along the teeth of the pinion or longitudinally along the axis of the shaft 10. In order to separate the parts, however, the end 20 of the arm 17 may be sprung far enough to allow it to pass within the elbow of the parts 18 and 18 so that the rack may pass from the-pinion. allowing the bearing loops 21 and 15 to slide alon the shaft. The pinion 13 is normally held in place along the shaft by friction, but may be driven ofi' when'necessary.

With the device arranged as shown in Fig. 1, it will serve admirably as an egg beater, rapid rotation being effected by gripping the members 17 and 18 and forcing them toward each other, whereby the rack will cause rapid rotation of the shaft 10 and heater 14, but when the gripis released upon said members, the compression of the springs 16 will cause them to separate and return to normal position at which time the rack will cause a rapid reverse rotation of the shaft and heater. A finger loop 18 is preferably formed in the member 18 so as to make the grip of the hand more secure.

The illustration of Fig. 3 shows an adaptation of the actuator 11 for the rapid rotation of a hand fan 22 secured to the outer end of the shaft 10'. The operation of the actuator in this form of the invention is precisely the same as that above described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a device of the character set forth, the combination of a shaft, a shrouded pinion secured adjacent one end of the shaft, and an actuator formed of a single piece of spring metal and having at its middle portiona bearing loo through which the shaft extends and being cut ad aeent thereto into a, plurality of spring coils, the parts of the actuator thence forming a pair of oppositely arranged hand grips and each terminating in an arm, the arm of one grip extending toward and substantially parallel to the other arm, one of said arms having a series of rack teeth meshing with said pinion and terminating in a hook over the other arm, and the arm opposite the rack terminating in bearing loop surrounding the shaft and lying adjacent the pinion.

2. In a device of the character set forth, the combination of a round wire shaft having a polygonal seat adjacent one end, a

, shrouded pinion fitted upon said seat, and

an actuator to rotate the shaft through said pinion, said actuator comprising a single piece of spring metal formed into a bearing loop at the middle portion thereof for cooperation with one portion of the shaft and having a pair of spring loops formed adj acent thereto, the two parts of the actuator thence forming hand grips and each having at the end thereof opposite the hearing loop an arm, the arm of one member extending toward and substantially parallel to the other arm, one arm having a series of rack teeth cooperating with saidfpinion and held by the shrouded pinion rom movement lengthwise of the shaft, said rack arm terminating in a hook limiting the relative movement between the grip members in one direction, and the opposite arm terminating in a bearing loop surrounding the shaft adjacent said pinion, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
